<code>
The <code> tag contains the verbatim source text of a
<program>. It is especially useful when a program
also has siblings such as <preamble> or
<tests>, or when the source is kept in a separate file.
If a <program> contains only code, the text may appear directly in the
program, but <code> makes the source block explicit.
